Can't find Halion on LE4 on Macbook Pro

Hi ¡¡
I recently installed LE4 on my new Macbook pro but every time I want to load a Halion sound the following message appears: “HalionOne: Can not find or load preset XXX”-
I checked in Pluggins Information, and Halion is there. In fact, I could even find HalionOne.vst in the Application Support Folder, in the Steinberg folder, in the VST2 folder.

I am new on Mac, so please if there is a solution, write it down as easy as possible…

Thanks and regards,
